exit.

between two server instances at server shutdown/startup.
This conflict on advisory locks appears to be the result of a bug
in the operating system; these locks should be released when the
files are closed, but somehow that does not always happen
immediately in Linux.  (Bug #9381)

"Early NULL-values filtering for ref access" (attempt2+post-review fixes)
1. update_ref_and_keys() accumulates info about null-rejecting
predicates in in KEY_FIELD::null_rejecting, add_key_part saves
these to KEYUSE.
2. create_ref_for_key copies them to TABLE_REF.
3. add_not_null_conds adds "x IS NOT NULL" to join_tab->select_cond of
appropiate JOIN_TAB members.

Includes code cleanups: 
* add_key_field() params: s/COND/Item_func/ (as only Item_funcs are
passed to it)
* add_key_fields() params: JOIN_TAB *stat removed (wasn't used)
